Approaches to Newcastle NSW Bathymetry Survey, 30m Resolution (2020-2021)

Bathymetry data for the seafloor east of the Approaches to Newcastle, New South Wales. The survey was acquired for the Australian Hydrographic Office by Guardian Geomatics onboard the MV Offshore Guardian between 4 December 2020 and 15 January 2021. Data was processed using Caris Hips & Sips software and exported as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Model seafloor topography based on the 30-meter resolution bathymetry grid.
• Analyze coastal and offshore geomorphology based on the high-resolution survey of the Newcastle approaches.
• Support marine habitat mapping and environmental studies based on detailed depth data.
• Integrate with other marine datasets for regional planning based on the geospatial coverage.

Strengths

• Data was acquired using a Kongsberg EM 2040-07 multibeam echosounder, suggesting high-quality sonar measurements.
• Survey has a defined temporal coverage from 4 December 2020 to 15 January 2021.
• Output is a 30-meter resolution, 32-bit floating point GeoTIFF, providing a standardized geospatial format.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is explicitly not to be used for navigational purposes, limiting its operational application.
